1.6.1 Configuring an Interface on the Local Switch to Send NTP Messages

Follow these steps to configure an interface on the local switch to send NTP messages:

Enter system view

Configure an interface on the

local switch to send NTP

If you have specified an interface in the ntp-service unicast-server or ntp-service

unicast-peer command, this interface will be used for sending NTP messages.

1.6.2 Configuring the Number of Dynamic Sessions Allowed on the Local

A single device can have a maximum of 128 associations at the same time, including

static associations and dynamic associations. A static association refers to an

association that a user has manually created by using an NTP command, while a

dynamic association is a temporary association created by the system during operation.

A dynamic association will be removed if the system fails to receive messages from it

over a specific long time.

In the server/client mode, for example, when you carry out a command to synchronize

the time to a server, the system will create a static association, and the server will just

respond passively upon the receipt of a message, rather than creating an association

(static or dynamic). In the symmetric mode, static associations will be created at the

symmetric-active peer side, and dynamic associations will be created at the

symmetric-passive peer side; In the broadcast or multicast mode, static associations

will be created at the server side, and dynamic associations will be created at the client

Use the command...
